LADLE CRANE.

Application filed September 20, 1918, Serial No. 254,993. Renewed March211, 1920. SeriaI No. 368,31.

An object of the invention is to provide an arrangement of ladle andcrane whereby an operator riding on the crane can easily manipulate boththe ladle and the crane from the operators cab.

Another object is to provide a ladle crane ot this kind which can bereadily reached from the ground.

Another object is to provide a ladle crane having these advantages andwhich at the saine time is simple and inexpensive to manufacture.

le'ferring now to the drawings,' i Figure 1 is a side elevation ot theladle crane showin part ol the framework broken away; and

l `ig. 2 is a corresponding end elevation.

The 'trame oi the ladle crane consists, as shown, of a beam 10,depending side mem bers 11 and 12, the bottom member 13 and the crossbraces 14 and 15.

rl`he ladle crane is preferably shown of the mono-rail type suspendedfrom a single I-beain, the lower flange of the lbeam forming rails uponwhich the wheels 17 of the One of these wheels is propelled through atrain of gears by the motor 18; this motor is controlled 'from theoperators cab as will hereinafter be explained. The motor 18 receivescurrent from a con- `veniently placed trolley wire 19througl1 the ll5swivel about this pin so that the crane is able-to follow a curved trackalthough the main 'trame beam 1s made long to allow a safe distancebetween the operators cageand the ladle.

i To the bottom of the depending member 1&2 is pivotally secured thebail ot the ladle 24. The ladle is mounted in the bail by means oftrunnions 25 formed on the ring 25, Within which the ladle is detachablysupported by engagement of its tapering `sides with the ring, one of thetrunnions carrying a worm wheel which is operated by means of a wormthrough the flexible shaft 27 and by means of the hand wheel 28 which islocated convenient to the seat 29 of the operators cab 30. Within easyreach of the operator is also placed the operating handle 31 of thecontroller 32. Both the operators cab and the ladle are placed near theground so that it is a very easy matter 'for the operator to step in andout oit the cab.

This ladle .is designed particularly ior use in a foundry for carryingmolten iron from the cupola to the smaller hand ladles which are usedfor pouring the molds.

lt will be seen from this description that l have produced a ladle cranewhich is very eliicient in service and which at the same time is verysimple and inexpensive to build.

lVhile l have shown and described but a single form ol my invention itis to be understood that it is capable of many modifications. Changestherefore in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims.

l claim- 1. ln a travelling ladle-crane, the combil nation of ahorizontal beam, trolley carriages swveled to the beam, means on thebeam for propelling one of the carriages, fixed members depending fromeach end of the beam, a ladle pivotally suspended from the end of onemember, an operators cage at the end of the other member, meansconnected to the ladle for tiltingit, and means Within the cage rforcontrolling the carriage propelling means and for actuating1 the tiltmgmeans.

2. In a travelling ladle-crane, the conibnation of a horizontal beam,trolley carriagessvviveled to the beam, fixed members depending fromeach end of the beam, ladle pivotally suspended from the end of onemember, an operator"s cage at the end ot ico y the other memher7 meansconnected to the ladle for tiltingrv it and actuating means thereforcomprising a hand-Wheel Within the cage and a jointed shaft connectingthe 5 hand-Wheel andy tilting means.

3. A ladle Crane comprising a ladle provided lWith trunnions, means fortiltably supporting the ladle on said trunnions, an operators cagefixed. on the support and means Within the cage and connected to one 10of said trunnions for tilting the ladle.

In testimony whereof I alix my signature.
